T all whom vmay ,comic-1m.'

Be it known that we, JOHN C. CoX and JOHN C. ALDRIDGE, citizens of the United States, and residents of Centralia, in the county of Marion and State of Illinois, have invented certain new and useful Improvements in -Car Couplings, of which the following is a specification.

This invention relates to car couplings and more particularly to couplings for use upon minel cars.

It is an object of this invention to provide a coupling which willbe easy to 1nanipulate, of few parts, simple in construction, yet strong and durable, and inexpensive to manufacture.

The device consists of a member having a bifurcated head, one end securely bolted to the floor of a car, the bifurcated head.

extending beyond the floor, the inner faces of each of the furcations being provided with aligned forwardly curved grooves, the upper ends of each of which open out upon the upper surface of the head. A T`shaped casting is provided for engagement in said grooves, the ends of the cross arm seating in the curved grooves, while the body is positioned between the furcations. The leg of the casing is provided with an aperture through which a link is passed for connection with the. leg of another casting of like construction as the first which same may be connected to a similar head on another car body or a clevis or other suitalle type of connection may be made use of at the other end.

A clear and better understanding may be had of the device upon reference to the accompanying sheet of drawing, in which Figure 1 is a top plan view,`partly in section, of the. device shown attached to the floors of two car bodies.

Figure 2 is a side view partly in vertical longitudinal section.

Figure 3 is a section of the connecting head, taken on the line 3 3, (if Figure l.

Figure 4 is a detail view of the T-casting and connecting link, and,

Figure 5 is a detail of the connecting head.

Referring now in detail to the various views of the drawing, in which like numerals indicate like parts in each of the several views, numerals 1-1, indicate the floor of a car and 2 the draw bar of the same. A member 3, is connected to the draw bar, and is provided with a transverse slot 4L into which the ,drlawwb'ar is positioned, suf, fcient space being provided between the up` per surface of the floor and the bar 2, to allow the under leg of the member 3 to be positioned therebetween. A suliicient number of bolts 5, are passed through the three members 1, 2 and 3 to securely hold the same together, the forward bolt passing through a binder 6, on the under surface of the car against which the nut is tightened.

The forward end of the member 3, which overhangs the car floor, terminates in an enlarged bifurcated connecting head 7, each of the furcations of which has formed in its inner face forwardly curved aligned grooves 8, which open upon the upper surface of the head near the rear of the fue cations as shown.

Connecting the cars by engagement with the heads 3, are T-shaped castings having a Hat body 9, of greater thickness at one end 9a, than at the othen The thickened ends of the castings are provided with lateral arms 10 which vare adapted to engage the grooves 8, the thickened part 9a, of the body 9, occupying the space between the furcations of the head 7. The end of 9, carrying the arms 10, is rounded, asshown, and increases in width .to the opposite end which is likewise rounded, this end being provided with an aperture 11, through which a connecting link 12, extends for connecting the castings.

In order that the grooves 8, be protected and to prevent `the arms 10, from riding up and out of the grooves should the connecting heads 7, come together, a cover plate 13 of the same contour as the head is attached thereto by a screw threaded bolt 11i, the head of which is raised sufficiently to allow the plate to be swung to one side when it is desired to disconnect the cars.

Having thus described the invention in accordance with the showing of the drawing, it is to be understood that various changes and modifications may be made in the structure without departing from the spirit of the invention as embodied in the claim.

that is claimed is y In a car coupling of the character described, a connecting member having one end formed to provide means for connection with a draw bar and having its other end enlarged and provided with a vertical slot to form a bifurcated head having the inner faces of the uroations parallel throughout, said inner 'faces of the furcations havingl formed therein grooves of equal Width throughout, each describing.;- an are `of approximately one quarter of a circle and extending from the upper surface of the hond adjacent the rear of the furent-ions, downwardly and forwardly in the face thereof, and a broad, flat connecting member having 10 laterally extending pins upon the longitudinal center of each side thereof, said member itting snugly between said parallel faces to prevent side movement of the member and said pins adapted to be so pocketed in said grooves as to be completely covered by the overlying` Walls thereof.

In testimony whereof, We affix our signatures hereto.
